MCP tools · 8 exposed · ~947 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
vanity_appraise ~136

Appraise how rare a Solana address is: its detected vanity pattern, rarity score, rarity bits, tier, and expected grind attempts. Pure math on the Base58 address — nothing is stored. If the address has been published to the proof-of-grind gallery, the public entry is returned too. Read-only, no payment.

NameTypeReqDescription
addressstringyesThe Base58 Solana public key to appraise (32–44 chars).
prefixLeninteger–Override how many leading characters to treat as the pattern prefix.
suffixLeninteger–Override how many trailing characters to treat as the pattern suffix.

No output schema declared.

No examples provided.

vanity_board ~166

Browse the public grind-bounty board: vanity-address bounties requesters have escrowed for the worker fleet to grind. Filter by status (open / all / settled), sort by recency, reward, or expiry, and paginate. Each bounty shows its pattern, USDC amount, difficulty, status, and timing. Read-only; posting a bounty is a separate x402-paid write on the HTTP API.

NameTypeReqDescription
limitinteger–Max bounties to return (1–100, default 24).
offsetinteger–Pagination offset (default 0).
sortstring–Order: newest first, biggest reward first, or soonest to expire. Default recency.
statusstring–Which bounties to list. Default open.

No output schema declared.

No examples provided.

vanity_config ~91

Read the grind-bounty market configuration: whether on-chain payouts are configured (can a winner actually be paid?), the settlement asset (USDC) and its decimals, which escrow networks are live (Base / Solana), the pricing band (floor + max atomics), the bounty protocol version, and the sealed-envelope scheme. Check this before posting to confirm the market can pay out. Read-only, no params.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

vanity_gallery ~180

Browse the public proof-of-grind gallery: rare Solana addresses people have published with a verifiable grind receipt. Sort by rarity score or recency, filter by tier, minimum pattern length, or a substring the pattern must contain, and paginate. Each entry shows the address, pattern, rarity score/bits, tier, and an explorer link. Read-only.

NameTypeReqDescription
containsstring–Only addresses whose vanity pattern contains this substring.
limitinteger–Max entries to return (1–100, default 24).
minLengthinteger–Only patterns at least this many characters long.
offsetinteger–Pagination offset (default 0).
sortstring–Order by rarity score (rarest first) or recency. Default score.
tierstring–Filter to a single rarity tier id.

No output schema declared.

No examples provided.

vanity_leaderboard ~66

Rank the worker fleet: the top grinders by total USDC earned from winning vanity-address bounties. Each entry shows a worker id and its cumulative payout. Read-only.

NameTypeReqDescription
limitinteger–How many top grinders to return (1–100, default 10).

No output schema declared.

No examples provided.

vanity_open ~97

List the open, unexpired bounties a grinding worker can race to claim — the queue worker fleets poll. Each entry carries the pattern to grind and the escrowed USDC reward; the first worker to submit a verified, sealed key wins. Read-only discovery; submitting a claim is a separate write on the HTTP API.

NameTypeReqDescription
limitinteger–Max claimable bounties to return (1–100, default 30).

No output schema declared.

No examples provided.

vanity_quote ~152

Quote how hard a Solana vanity address is and what to escrow for it. Give a Base58 prefix and/or suffix and get the expected attempts, rarity tier, and an honest suggested USDC bounty (atomic units) from the difficulty→price oracle. Pure function of the pattern — no wallet, no payment, fully read-only. Use this before posting a grind-bounty so you escrow a fair amount.

NameTypeReqDescription
ignoreCaseboolean–Match the pattern case-insensitively (cheaper, less rare). Default false.
prefixstring–Base58 prefix the address must start with (e.g. "THREE").
suffixstring–Base58 suffix the address must end with.

No output schema declared.

No examples provided.

vanity_stats ~59

Get live totals for the grind-bounty market: how many bounties are open, how much USDC is currently escrowed, and how much has been paid out to winning workers. A quick pulse on market activity. Read-only, no params.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.
